Rockstar🎓
Top SchoolBoaz Ben-zvi is an expert engineer with 9 years in his current trajectory and over three decades of deep systems and database engineering experience, based in Sunnyvale, California. He has repeatedly delivered high-impact execution-engine and resource-management improvements at companies including Hewlett Packard Enterprise, MapR (as an Apache Drill committer/PMC member), Actian, and HP. His work spans memory management, spill/retry strategies, storage persistence redesigns and security/configuration for distributed data fabrics—recently contributing to FIPS 140-2 Level 1 compliance and customized Zookeeper for cross-cluster setups. He is an active back-end contributor to the well-known Apache Drill project, improving stability and out-of-memory handling in core query operators. Known for pragmatic, low-level innovations (including patented and production-proven operators and profiling tools), he combines a strong academic foundation from Technion and MIT with a track record of solving hard performance and scalability problems. Colleagues rely on him for technical ownership of thorny bugs, predictable large-query behavior, and architecture changes that measurably improve system throughput and reliability.
